Times (s) 30, 90, 150

Number of Wing beats
420, 1,260, 2,100

How many times will a mockingbird beat its wings in 2 minutes? Enter the number in the box.

1680

Step-by-step explanation:

90 sec + 30 sec = 120 sec (2 minutes)

1260 beats + 420 beats = 1680 beats

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
